LibreOffice: an open-source Office Suite (Free program)
LibreOffice is an open-source office suite alternative to commercial office suites such as Microsoft Office, Apple Office apps, and OnlyOffice.
It is the successor to OpenOffice.org suite, the primary office suite for many Linux distros.
LibreOffice is compatible with a wide range of document formats such as Microsoft® Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx), and Publisher. But LibreOffice goes much further with its native support for a modern and open standard, the Open Document Format (ODF). With LibreOffice, you have maximum control over your data and content – and you can export your work in many formats including PDF.
LibreOffice Primary apps
LibreOffice suite is consisting of several apps that make its user not require any apps outside their app scope.
Writer: Word Processor
Writer is the official word and document processor for LibreOffice, and the equivalent of MS Word. It is quite similar to all popular Word processors, yet it comes with better file compatibility.
Writer has all the features you need from a modern, full-featured word processing and desktop publishing tool. It’s simple enough for a quick memo, but powerful enough to create complete books with contents, diagrams, indexes, and more. You’re free to concentrate on your message, while Writer makes it look great.
